Assisi is the 21-year-old daughter of Jade Jagger, Mick's 42-year-old offspring, who is also expecting a baby boy next month.

"The women in our family just tend to have children young, it runs in the genes," said Assisi.

"I grew up quite quickly and wouldn't have considered having a child if I was doing what my friends are doing at this stage, messing around. I don't drink, I don't smoke and I'm very settled," she added.
